This function enables the user to fit two models and compare their deviations. This function can fit the parts before and after springback, and compare the springback magnitude of parts. The interface is illustrated in Figure 9.6.1
Figure 9.6.1 Best fit interface
SOURCE: the model to be moved during fitting.
ADD: Add parts to the model list. Click this button to display the Select Part dialog box and select the required parts. It is allowed to add multiple parts.
REMOVE: Remove parts from the list. Select parts in the list and click the REMOVE button.
SURFACE ONLY: Only operates surface. If this function is toggled on, the best fit is only operated on the defined model surface without moving other objects. If there is no surface in the model, this function is grey.
DEFINE REGION: Define region as the fitting base for best fitting. If the fitting region is defined, the program will only use the defined region as a base to fit during best fitting of two models. Otherwise, it will use the whole model as fitting base. If the model is large, it is suggested to define a region for improving the calculation velocity.
DEFINE LCS: Define LCS as the fitting base for best fitting. When fitting two models, the program will take the defined LCS as the base for fitting. Refer to Section 2.5 Local Coordinate System for detailed description about defining LCS.
FLIP: The source model begins to fit after rotating 180° about X, Y and Z axis. This option is enabled after defining the source model.
TARGET: Define the target part which does not move during best fitting.
DEVIATION CHECK: Check the deviation of two models after best fitting. Refer to Section 9.5 for a detailed operations.
